The Canadian Superior Province has become one of the key test pieces to discuss tectonic processes and mechanisms crustal growth in Late Archean. consists a >2.8 Ga proto-cratonic core intruded by voluminous arc-like plutons surrounded series narrow, elongate ca. 2.8–2.7 juvenile belts, also referred as terranes or domains. seem wrap around generally young outward, but kinematics geodynamic cau...

In two earlier papers (Wallace et al., 1983, 1985), we discussed the evidence for tectonic release from underground nuclear explosions on Pahute Mesa at the Nevada Test Site (NTS) as observed in long-period body waves. It has been shown for some time that the nonisotropic component of the surface waves from most of these events could be explained by an equivalent double-couple source; namely st...

Introduction: Dione (1124 km in diameter) is a mid-sized icy moon of Saturn which shows a wide range in tectonic features across its surface revealing an intense geologic history. With the two highly evolved satellites Enceladus und Titan, Dione forms a set of three satellites whose surfaces have been shaped by tectonic activity on a global, not only on regional scale. Tectonic forms on Dione w...

Abstract Delineation and characterization of the intraterrane shear zones (ITSZs) are very significant in establishing suitable models to understand tectonic evolution continental blocks often provide crucial information on supercontinent assembly. The granitoid rocks Bundelkhand Craton (BC) host mesoscale ductile varying width direction typically represent decoupling (high low strain), charact...

Large-scale strike-slip faults are associated with significant strain partitioning in releasing/restraining bends and often display map-view curvatures ending horse-tail geometries. Such commonly indentation tectonics, where shortening front of indenters is transferred laterally to transpression, the formation transtensional/extensional basins. We investigate how these structurally distinct dom...

How fold and thrust belts (FTBs) evolve over time space in a transpressional regime remains poorly understood. Based on high-resolution 3D seismic reflection data remote sensing images, we herein present detailed structural analysis of the Cenozoic faults NW margin Qaidam Basin that is bounded to north by left-reverse Altyn Tagh fault system. Two sets orthogonal, basement-involved with contrast...

Introduction: Planar deformation features (PDFs) in quartz are diagnostic impact evidence. Using light microscopy, it is often impossible to distinguish between PDFs and tectonic deformation lamellae. [1] showed that PDFs can be imaged using a cathodoluminescence (CL) detector in a scanning electron microscope (SEM) and that in SEM-CL images PDFs can be distinguished from tectonic microfracture...

The surface of Venus displays several tectonized terrains in which the morphologic characteristics of the original materials are almost completely erased by superposed tectonic structures whose large dimensions (»100 km) suggest formation related to mantle convection. The characteristics of these tectonized terrains are in contrast to volcanic units in which tectonic structures are less signifi...
